In celebration of the weekend, both The Barnes Foundation and The Philadelphia Museum of Art open their doors tonight for after-hours art, drinks, music and more.

And definitely make plans to hang out at Spruce Street Harbor Park the awesome pop-up park on the waterfront, before it closes for the season next weekend. Have dinner at the floating Garces restaurant, sip a beer in the beer garden or play games along the boardwalk.

Also, don’t miss the very cool exhibition about Frank Gehry’s Master Plan for the Philadelphia Museum of Art – Making a Classic Modern – which runs through Monday, September 1 (leaving only a little over a week to take in the exhibition!).
